The output end of the electric cylinder 5 penetrates through the horizontal top plate 4 and is fixedly connected with a square frame 6. Two drive motors 11 are fixedly connected to the back surface of the square frame 6. The output end of each drive motor 11 penetrates through the square frame 6 and is fixedly connected with an oil coating roller 12. The inner bottom wall of the square frame 6 is fixedly connected with an oil guide pipe 9. A plurality of oil injection heads 10 are fixedly communicated with the outer surface of the oil guide pipe 9. One end of the oil guide pipe 9 penetrates through the square frame 6 and is fixedly communicated with an inlet pipe 13. An arc groove 14 is opened on the upper surface of the bearing platform 1. The inner wall of the arc groove 14 is rotatably connected with a rotating round roller 15 through a bearing; specifically, the operation of the electric cylinder 5 is used to push the square frame 6 to move up and down, so that when the square frame 6 moves, it can drive the drive motor 11 and the oil coating roller 12 to move up and down, and then the distance between the rotating round roller 15 and the oil coating roller 12 can be adjusted, so that it can be adjusted for use according to PET sheets of different sizes, and is suitable for oil coating of PET sheets of more sizes. With the provided rotating round roller 15, the PET sheets can be oil-coated while rotating, achieving the purpose of more convenient oil coating;

[0026] In this embodiment, a plurality of oil leakage round holes 16 are formed in the bottom surface of the bearing platform 1, and each oil leakage round hole 16 penetrates into the inside of the arc-shaped groove 14. A plurality of T-shaped legs 2 are fixedly connected to the bottom surface of the bearing platform 1; two arc-shaped supporting blocks 17 are fixedly connected to the upper surface of the bearing platform 1, and the two arc-shaped supporting blocks 17 are respectively located on the left and right sides of the bearing platform 1; the right side surface of the square frame 6 is hinged with an oil scraping plate 8 through a rotating shaft, and a plurality of telescopic springs 7 are fixedly connected to the outer surface of the oil scraping plate 8, and one end of each telescopic spring 7 away from the oil scraping plate 8 is fixedly connected to the outer surface of the square frame 6; specifically, through the arranged oil leakage round holes 16, the excess grease during oil coating can leak out from the oil leakage round holes 16, and it is convenient to collect the excess oil liquid, which has the advantage of being convenient for collecting waste oil.

At the same time, the driving motor 11 is started to drive the oil coating roller 12 to rotate, and oil is sprayed through the oil guiding pipe 9 and the oil injection nozzle 10, so that the oil is evenly coated on the surface of the PET sheet by the rotation of the oil coating roller 12, realizing the oil coating treatment of PET sheets of different sizes.
